Analysis of information sources in references of the Wikipedia article "Nsibidi" in English language version.
The Ejagham developed a unique form of ideographic writing, signs representing ideas and called nsibidi, signs embodying many powers, including the essence of all that is valiant, just, and ordered ... The late king of Oban in southern Ejagham told me in the summer of 1978 that nsibidi emerged in the dreams of certain men who thus received its secrets and later 'presented it outside'.
Perhaps it is allowable to mention here that the Ekoi claim to have originated this script, of which several hundred characters and a considerable number of complete stories were collected during our stay ... Among the Uyanga also it has unfortunately been impossible to find any trace of the interesting legend alluded to above [that the script originated in this area, as recorded by MacGregor], whereas ... the Ekoi, who certainly have a strong Bantu strain, claim, and with what seems good grounds, to have originated the whole system. At the present day a greater variety of signs seems to exist among the Ekoi of the interior than amid any other tribe.
Scholars believe that nsibidi originated among the Ejagham, who use it more extensively than any other group in the region. The spread of nsibidi may have been a result of Ejagham migrations or their practice of selling the secrets of the Ejagham men's Leopard Society (Ngbe) to their neighbors (the Igbo, Efik, Ibibio, Efut, Banyang, and others).
